(click here to know more about CDO).INNER RAINBANDS - over water (South China Sea)...not yet affecting any land areas...will reach the coastal areas of Western Guangdong & Eastern Hainan late Monday or early Tuesday.Tropical Storm Conditions with Tropical Storm Force Winds (62-94 kph) will be expected along these bands. OUTER RAINBANDS - affecting & spreading across Hainan and Southern China particularly Guangdong Province.Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands (click here to know more about Rainbands).24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 200 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 201 to 400 mm (high to very high) along areas near the center of Vicente (Ferdie).
